This is a hard one. This book is interesting, engaging and so much more. But if had to pick one thing, it would probably be the society they live in. Maybe I like it because of how different it is, or maybe I like it because it contributes so much to the story. To sum it up, the society is divided into colors. The main character starts out as the lowest color, red. In the story Darrow climbs from red to gold to help change the society. Me and my father like to give people certain colors depending on their personality. Overall I find it just incredibly interesting.
